MICHAEL JAMES DAVIN, F DANVILLE, ILLINOIS.

MOLD.

Application led December 9, 1922.

To all whom t may concern.'

Be it known that I, MICHAEL JAMES DAVIN, a citizen of the United States,residing at Danville, in the county of Vermilion and State of Illinois,have invented new and useful Improvements in Molds, of which thefollowing is a specification.

This invention relates to a wall form or mold, the general object of theinvention being to provide means whereby the four walls of a buildingcan be poured at one time.

Another object of the invention is to form the corners of greatthickness so that these corners will act as columns and strengthen thebuilding.

Another object of the invention is to form an air space in the walls andto provide means for connecting the walls on each side of the spacetogether.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specically pointed out in the appended claim.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is a sectional plan view of a building constructed in accordance withthis invention.

Figure 2 is a vertical sectional view through the building.

Figure 3 is a longitudinal sectional view through one of the walls andshowing the forms in position.

Figure 4; is a section on line 4-4 of Figure 3.

Figure 5 is a face view of a portion of one of the forms.

Figure 6 is a view of the opposite face of said form.

Figure 7 is a sectional view showing how the corners of a building areconstructed.

Figure 8 is a view showing how a window opening is formed.

The remaining figures are detail views.

In these views 1 indicates the forms which are arranged in sections,each section being composed of the flange 2 formed of anglev iron or thelike, the corrugated sheets 3 and the plain sheets 4, the sheets Sbeinginter- Serial N0. 605,899.

posed between the sheets 4 and the frame. This construction insuresgreat strength and the sections may be secured together in any desiredmanner. The forms are so placed that an interior space 5 is arrangedwithin each wall 6, and the inner forms 1 have links 7 connectedtherewith and the inner ends of these links are connected with thevertical bars 8 so that by pulling the bars 8 upwardly the forms 1 willbe moved toward each other and away from the finished walls, thuspermitting the forms to be removed. Tie bars 9, formed of cement or thelike, extend throu h the space 5 and have their enlarged ends ocated inthe space between the forms 1 and 1 so that these enlarged ends will beembedded in the concrete as the walls are formed so that the two wallswill be connected together. Nuts 10 are carried by the tie bars 9 androds 11 have their threaded ends engaging said nuts, these rods 11acting to support the outer forms 1. When the forms are to be removedthese rods can be unscrewed and taken out and then the holes plugged sothat the walls are not marred by the tie bars. Slotted plates 12 engagethe ends of the tie members 9 and act to bridge the spaces between themold sections 1 so that these sections can be spaced apart a sufficientdistance to prevent the tie members 9 from interfering with theirremoval. Angle plates 13 are placed at the corners of the forms and theedges of the inner form at these corners are spaced quite a distanceapart and this space bridged by the narrow section 14 so that thecorners of the building will be of great thickness to produce columns 15which greatly strengthen the building. Window openings 16 may be left inthe walls by placing plates 17 at the edges of the forms where thewindow is to be located.

By this invention a house can be easily and quickly constructed and byreason of the space in the walls it will be cold and heat proof. Thewalls and floors may be reinforced by metal in the usual manner. A sheetof paper, shown at 18, may be used on the face of the inside form torevent it from sticking to the finished wa l.

It is thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent. f

I desire it to be understood that l may make changes in the constructionand in the combination and arrangement of the several parts, providedthat suchfchangesfall Within the scope of the appended claim.

Vhat I claim is A building' form consistingof inner and outer pairs ofsections having their inner pairs spaced apart to form an air space andthe inner sections having inclined corners to make the corners of thebuilding of great 10 thickness, means for tying the two parts of havingthreaded@ parts` engaging the nut 15 members Yfor tying the outer formsin place.

In testimony whereof I alix my signature.

MICHAEL JAMES DAVIN.
